Providing in- ground valuations is a breach of the JORC code guidance clause 51 for the reporting of mineral resources. Delta does not endorse the valuation of $93B and warns investors that they should not rely on the valuation information contained within the article when making their investment decisions as the information was prohibited under the JORC Code (2012). Delta requests that this announcement lift the trading halt in its securities. This request has been authorised for release to the ASX by the James Croser, Managing Director of Delta Lithium Limited.
